Functional MRI
This imaging technique produces MRI scans in a faster sequence than traditional MRIs. The increased speed allows areas of the brain to "light up" on scan when the patient is asked to perform a task such as moving a finger, moving toes or feet, or speaking. This helps identify the  "function" of specific areas of the brain, and is useful for preoperative surgical planning and intraoperative avoidance of these areas if possible. This imaging technique is also called echoplanar, real time, or Fast MRI.
